Will a strap close on your wrist?

Set for this watch: 38 mm of case and 18 mm between the lugs. Add your wrist and see where a standard strap would close.

Filled in with the case diameter, which is what we hold for this reference. Measure the watch tip to tip for the exact answer: it is usually a few mm more.

Sizing notes

  • 18 mm is the gap between the lugs, so a 18 mm band goes in without adapters. Whether it sits flush against a 38 mm case depends on how that case is shaped.
  • 18 mm is not a common size: only 3,965 of the 41,485 watches measured take it (9.6%), so ready-made choice at this width is narrower than at 20 or 22 mm. Every watch that takes 18 mm →
